Answer 2

The maximum bending moment is 25 kN/m

Given,

length of beam, l = 5m

weight of load, W = 30 KN

To Find,

Maximum bending moment

Solution,

A structural element's potential to bend as a result of an external force (or moment) is measured by a bending moment (BM).

This idea is crucial to structural engineering because it enables you to determine where and how much bending might happen when forces are applied.

When shear force is zero or changes sign, the bending moment is at its highest (positive to negative or vice-versa).

Mathematically, the maximum bending moment is given by:

M(max) = (W×l)/6

⇒ M(max) = (30×5)/6

⇒ M(max) = 5×5

⇒ M(max) = 25 kN/m
